Tubular Containers, and Sheets,.;of which the following is a specification.

' One object of my presentinvention is the provision of a, rocess for economically, accurately and't oroughly tempering. tubes, tubular containers and sheets ,or plates, as well'as; other metallic articles which are or-- dinarily subjected to the tempering. operation.

Another objbct of the invention is the pro-.

vision of imp oved and materially advan-' tageous means for carrying out the process. To the attainment of the foregoing, the invention-consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof Figure 1 is a transverse section of an apparatus for tempering bottles, containers or tubes in accordance with my invention.

.2 is. a similar view tionfor the same purpose. v

Figure 3 is a transverse section of a modification for tempering metallic sheets or of a. modifica plates in. accordance with my invention.

The .ohief characteristic of my invention resides 1n the interpositio "of a heat collect ing medium between a c' olingpr tempering means and the article that is being tempered,

the said medium serving to isolate the cool-.

ing or tempering means from the articlethat 1 is being temperdand also serving by vlrtue of its conductivity to take heat from the arv title that is being-tempered and give oil such 'duced into the tank 1 through a/pipe 3,'and

- .through a pipe 4, equipped with a relief. Ml

heat to the cooling or tempering means.

In Figure 1 of the drawings the apparatus includes a tank 1' for the cooling or tempering means 2 which may be water or any other-approprlate agent. Water s introrvater is discharged from "the said tank valve 5--i.' e., a valve adapted to open under a predetermined pressure so as topermit waterto pass from the tank 1 and also with a view to maintaining a certain predetermined pressure in the tank 1. v

- .Patentea June a, 1922.

IJThe tubular article 16 'shown in positionto be tempered may obviously be a metallic container such asa bottle, or mayhe'a pipe 7 1 or any other tubular article. In order'to temipered the sald article 6 is positioned as illustrated in the conductive medium 7 for collecting or taking heat'from the article 6 and giving off such-heat to the cooling or tempering means 2. The said medium 7 is preferably formed of copper, though I .would have it distinctly. understood that it' may be formed of any other material compatible with its defined function without involving departure" fromthe s'co e of'my mventlon as claimed. Said med? um 7 1s contractible under. the pressure of the means 2 in the tank 1, and is also expansible when relievedof lar portion a made upv of arcuate sections, and flanges 'Wcxtending outwardly fromthe endsof the sections 7 and connected together at 7 so that the several sections 7 form a circular series. Y

Manifestly'an article such as the article 6 7, and when it is so introduced an operator may, by controllm the pressure of. the

against the article 6 with'the result that the tempering may be nicely governed hy the ressure. ,It comprises a circumay be readily introduced into themedium operator aslregards the be and ending and the duration of the tempering.

Inv the modification shown in Figure 2 the tank for the cooling or tempering means 2 is in two sections 1*, which are appropriately fixed with respect to each other and are provided with inlet and outlet pipes 3 and 4 .for. water or other cooling or tempering agent and have their opposed walls formed by heat 1 collecting med1um 7",'preferahly 7 is provided with anintermediate arcuate tively arranged as illustrated in order to retempered.

- copper. Each of the said mediums or walls portion 7, "and the two portions? are rela- It will be apparent that by controlling the I pressure of the means 2 in the tanks 1'' an operator isenabled to crowd the portions 7 of the mediums ,Wagainst the tubular article 6 to a greater or less extent as difierent conditions re uire. I

Theemboent shown in Figure 3 is for ice which is shown and numbered 6. embodiment is similar to that shown 1n F1g-/ thetem ering of sheets or'plates one of p The said are 2 except that the conductive heat collecting medium 7 preferably of copper are flat in form. e operation of this emh'odl ment, however, isgenerally similar to that of the embodiment shown m Figure 2.

- It will be apparent from the foregoing that in the several embodiments illustrated a heat collecting medium in contact with j the article to be tempered serves to take heat from the said article and also serves to give ofl' such heatto the coollng'or tempering means while keeping such means out of direct contact with the article to be tempered It will also be apparent that in each and all claim and desire to secure by Letters-Patent, is 2- 1. The process of temperingmetallic articles which consists in interposmg a conductive medium between an article to be tem-' pered and an elastic cooling or tempering means and utilizing the elastic coolmg or tempering means for the regulation of the .pressure that the said medium exerts against the article to be tempered.

2. Means for tempering metallic articles, compnsm closed containing means for elastic coo ing or tempering means, and sectio'nal conductive means carried by saidicontaining means to 'segregate'the cooling or tempering means'frojm the articleto' be tempered and'to take heat from said article and give ofi the heat to the cooling or tempering means; the said sectional conductive means heingsubject to pressure of the elasticcoolmg or tempering means in opposite dlrec- .tions against an article to be tempered.

In testimony whereof I aiii'x my signature.
